The Russians are here to stay — that was the motto of the Russian engineers who designed the Vladivostok Fortress. The VoroshilovBattery was erected in just two years, from 1932 to 1934. It includes two turret mounts taken from battleship Poltava. The turret — weighing 900 tons — can be rotated manually, you only need ten men for this. A coastal fortress that didn't fire a single shot in a war —because the enemy thought that they were at a disadvantage and would not dare to attack it. It is this silence in times of war that made it extraordinarily successful.

The Atlantic Wall or “Atlantikwall” in German was an extensive system of coastal defences and fortifications reaching from the South of France to the Northern parts of Norway. In some areas the defenses were quite formidable, whereas in others areas they were lacking. In this video I give you a short overview on the French parts of the Atlantic Wall and then show you how an individual infantry division was setup for coastal defense.

Audio visual production from the Centro de Diseño y Producción de Recursos Instruccionales (CEDPRI) de la Universidad de Puerto Rico en Humacao. The half-hour documentary film was made by Dr. Gerardo M. PiñeroCádiz in 2013 and tells the story of preparing the island of Puerto Rico for the coming of war. All kind of media allow the spectator to understand, examine and protect the surviving elements of these awesome defenses. The film aims to rescue from oblivion the defensive sites built by the U.S. ArmyCorps of Engineers on the island of Puerto Rico during the 1940s, and their relation to other military installations. We will also highlight their importance during the war emergency and briefly explain their operations.
Just months into World War II, the United States would grant Puerto Rico the same strategic importance that the Spanish Empire had given it in the past. The “Gibraltar of the Caribbean” had just become one of the most important parts of American defense system in the West Indies. Air bases, naval and ground systems, communications, roads, and all kinds of military installations transformed Puerto Rico into one of the most important strategic points in the Atlantic for the successful defense of commercial maritime routes, the Allied supply lines, troop movements, Caribbean oil transit, and the Panama Canal itself.
To protect the military facilities, already built or under construction, from ground, aerial or naval attack, or sabotage, it was agreed to start the deployment of defenses, such as the coast artillery. Aside from protection, these defenses would lend support to ships while approaching, in transit, or sailing away from Puerto Rico.

intro is a AuthenticWW2German air-raid siren as used on the bunkers around the coast.
Clips from recent film trip to Guernsey July 2018 for research and mapping the area & details maps in the making of our film we are producing.

A bit of History:
in 1940The Germans did not realize that the islands had been demilitarized and they approached them with caution.
The GermanLuftwaffe Reconnaissance flights were inconclusive.
But late at night on 28th June 1940, they sent a squadron of bombers over the islands and bombed the harbours of Guernsey and Jersey.
In St. Peter Port, the main town of Guernsey, some lorries lined up to load tomatoes for export to England were mistaken by the reconnaissance flights for troop carriers !
A similar attack occurred in Jersey where 9 died.
In total, 44 islanders were killed in the raids.
The BBC broadcast a belated message that the islands had been declared "open towns" and later in the day reported the German bombing of the island.
While the Wehrmacht was preparing Operation Grünpfeil (Green Arrow), a planned invasion of the islands with assault troops comprising of:
2 battalions
A reconnaissance pilot, Hauptmann Liebe-Pieteritz, made a test landing at Guernsey's deserted airfield on 30th June to determine the level of defense. There was none what so ever !
He reported his brief landing to Luftflotte which came to the decision that the islands were not defended.
A platoon of Luftwaffe airmen was flown that evening to Guernsey by Junkers transport planes.
Inspector Sculpher of the Guernsey police went to the airport carrying a letter signed by the bailiff stating that "This Island has been declared an OpenIsland by His Majesty's Government of the United Kingdom.
There are no armed forces of any description. The bearer has been instructed to hand this communication to you. He does not understand the German language."
He found that the airport had been taken over by the Luftwaffe.
The senior German officer, MajorAlbrecht Lanz, asked to be taken to the island's chief man.
They went by police car to the Royal Hotel where they were joined by the bailiff, the president of the controlling committee, and other officials. Lanz announced through an interpreter that Guernsey was now under German occupation.
In this way the Luftwaffe pre-empted the Wehrmacht's invasion plans.
Jersey surrendered on 1st July 1940.
Alderney, where only a handful of islanders remained, was occupied on 2nd July and a small detachment traveled from Guernsey to Sark, which surrendered on 4th July 1940.
The first ship-borne German troops consisting of two anti-aircraft units, arrived in St. Peter Port on the captured freighter SS Holland on 14th July 1940.
The German forces quickly consolidated their positions.
They brought in infantry, established communications and anti-aircraft defenses, established an air service with occupied mainland France, and rounded up British servicemen on leave.
The Channel Islands were amongst the most heavily fortified parts of the Atlantic Wall, particularly Alderney which is the closest to France.
On 20th October1941Hitler signed a directive, against the advice of Commander-in-Chief von Witzleben, to turn the Channel Islands into an "impregnable fortress".
In the course of 1942, one twelfth of the resources funneled into the whole Atlantic Wall was dedicated to the fortification of the Channel Islands.
Hitler had decreed that 10% of the steel and concrete used in the Atlantic Wall go to the Channel Islands.
It is often said the Channel Islands were better defended than the Normandy beaches, given the large number of tunnels and bunkers around the islands.
By 1944 in tunneling alone, 244,000 cubic meters (8,600,000 cu ft) of rock had been extracted collectively from Guernsey, Jersey, and Alderney (the majority from Jersey).
At the same point in 1944 the entire Atlantic Wall from Norway to the Franco-Spanish border, excluding the Channel Islands, had extracted some 225,000 cubic meters (7,900,000 cu ft)
.
Most of the WW2 Bunkers and Command posts are easily accessible and contain a wealth of information and construction details like authentic air vent systems in bunker walls along with 1940's trenches leading to the battery guns and sleeping quarters
Guernsey is well worth a visit - with many of the 1940's Bunkers being re-opened and restored with authentic German WW2 field gear.
.

Hitler ordered the construction of the fortifications in 1942. Almost a million French workers were drafted to build it. The wall was frequently mentioned in Nazi propaganda, where its size and strength were usually exaggerated. The fortifications included colossal coastal guns, batteries, mortars, and artillery, and thousands of German troops were stationed in its defences. When the Allies eventually invaded the Normandy beaches in 1944, most of the defenses were stormed within hours. Today, ruins of the wall exist in all of the nations where the wall was built, although many structures have fallen into the ocean or have been demolished over the years.

Background

Puerto Rico

Puerto Rico (English /ˌpɔːrtəˈriːkoʊ/ or /ˌpwɛərtəˈriːkoʊ/;Spanish:[ˈpweɾto ˈriko], locally also[ˈpwelto ˈχiko; ˈʀ̥iko]), officially the Commonwealth of Puerto Rico (Spanish:Estado Libre Asociado de Puerto Rico, literally the "Free Associated State of Puerto Rico"), is a United Statesterritory located in the northeastern Caribbean. Puerto Rico is an archipelago that includes the main island of Puerto Rico and a number of smaller islands. The capital and largest city is San Juan. The territory does not observe daylight saving time, and its official languages are Spanish, which is predominant, and English. The island's population is approximately 3.4 million.

Puerto Rico's rich history, tropical climate, diverse natural scenery, renowned traditional cuisine and attractive tax incentives make it a popular destination for visitors from around the world. Its location in the Caribbean, combined with centuries of colonization and subsequent migration, has made Puerto Rican culture a distinct melting pot of Amerindian, Spanish, African, and North American influences.

Puerto Rico can be played by three to five players, although an official two player variant also exists. There is an official expansion which adds new buildings that can be swapped in for or used along with those in the original game. In February 2004, Andreas Seyfarth released a separate card game called San Juan based on Puerto Rico and published by the same companies. Puerto Rico is one of the highest rated games on BoardGameGeek.

Gameplay

Each player uses a separate small board with spaces for city buildings, plantations, and resources. Shared between the players are three ships, a trading house, and a supply of resources and doubloons (money).

Both Bailiwicks have been administered separately since the late 13th century; each has its own independent laws, elections, and representative bodies (although in modern times, politicians from the islands' legislatures are in regular contact). Any institution common to both is the exception rather than the rule.

The Russians are here to stay — that was the motto of the Russian engineers who designed the Vladivostok Fortress. The VoroshilovBattery was erected in just two years, from 1932 to 1934. It includes two turret mounts taken from battleship Poltava. The turret — weighing 900 tons — can be rotated manually, you only need ten men for this. A coastal fortress that didn't fire a single shot in a war —because the enemy thought that they were at a disadvantage and would not dare to attack it. It is this silence in times of war that made it extraordinarily successful.

The Atlantic Wall or “Atlantikwall” in German was an extensive system of coastal defences and fortifications reaching from the South of France to the Northern parts of Norway. In some areas the defenses were quite formidable, whereas in others areas they were lacking. In this video I give you a short overview on the French parts of the Atlantic Wall and then show you how an individual infantry division was setup for coastal defense.

Ethan Meixsell - Demilitarized Zone (the Irony :D)

Audio visual production from the Centro de Diseño y Producción de Recursos Instruccionales (CEDPRI) de la Universidad de Puerto Rico en Humacao. The half-hour documentary film was made by Dr. Gerardo M. PiñeroCádiz in 2013 and tells the story of preparing the island of Puerto Rico for the coming of war. All kind of media allow the spectator to understand, examine and protect the surviving elements of these awesome defenses. The film aims to rescue from oblivion the defensive sites built by the U.S. ArmyCorps of Engineers on the island of Puerto Rico during the 1940s, and their relation to other military installations. We will also highlight their importance during the war emergency and briefly explain their operations.
Just months into World War II, the United States would grant Puerto Rico the same strategic importance that the Spanish Empire had given it in the past. The “Gibraltar of the Caribbean” had just become one of the most important parts of American defense system in the West Indies. Air bases, naval and ground systems, communications, roads, and all kinds of military installations transformed Puerto Rico into one of the most important strategic points in the Atlantic for the successful defense of commercial maritime routes, the Allied supply lines, troop movements, Caribbean oil transit, and the Panama Canal itself.
To protect the military facilities, already built or under construction, from ground, aerial or naval attack, or sabotage, it was agreed to start the deployment of defenses, such as the coast artillery. Aside from protection, these defenses would lend support to ships while approaching, in transit, or sailing away from Puerto Rico.

A bit of History:
in 1940The Germans did not realize that the islands had been demilitarized and they approached them with caution.
The GermanLuftwaffe Reconnaissance flights were inconclusive.
But late at night on 28th June 1940, they sent a squadron of bombers over the islands and bombed the harbours of Guernsey and Jersey.
In St. Peter Port, the main town of Guernsey, some lorries lined up to load tomatoes for export to England were mistaken by the reconnaissance flights for troop carriers !
A similar attack occurred in Jersey where 9 died.
In total, 44 islanders were killed in the raids.
The BBC broadcast a belated message that the islands had been declared "open towns" and later in the day reported the German bombing of the island.
While the Wehrmacht was preparing Operation Grünpfeil (Green Arrow), a planned invasion of the islands with assault troops comprising of:
2 battalions
A reconnaissance pilot, Hauptmann Liebe-Pieteritz, made a test landing at Guernsey's deserted airfield on 30th June to determine the level of defense. There was none what so ever !
He reported his brief landing to Luftflotte which came to the decision that the islands were not defended.
A platoon of Luftwaffe airmen was flown that evening to Guernsey by Junkers transport planes.
Inspector Sculpher of the Guernsey police went to the airport carrying a letter signed by the bailiff stating that "This Island has been declared an OpenIsland by His Majesty's Government of the United Kingdom.
There are no armed forces of any description. The bearer has been instructed to hand this communication to you. He does not understand the German language."
He found that the airport had been taken over by the Luftwaffe.
The senior German officer, MajorAlbrecht Lanz, asked to be taken to the island's chief man.
They went by police car to the Royal Hotel where they were joined by the bailiff, the president of the controlling committee, and other officials. Lanz announced through an interpreter that Guernsey was now under German occupation.
In this way the Luftwaffe pre-empted the Wehrmacht's invasion plans.
Jersey surrendered on 1st July 1940.
Alderney, where only a handful of islanders remained, was occupied on 2nd July and a small detachment traveled from Guernsey to Sark, which surrendered on 4th July 1940.
The first ship-borne German troops consisting of two anti-aircraft units, arrived in St. Peter Port on the captured freighter SS Holland on 14th July 1940.
The German forces quickly consolidated their positions.
They brought in infantry, established communications and anti-aircraft defenses, established an air service with occupied mainland France, and rounded up British servicemen on leave.
The Channel Islands were amongst the most heavily fortified parts of the Atlantic Wall, particularly Alderney which is the closest to France.
On 20th October1941Hitler signed a directive, against the advice of Commander-in-Chief von Witzleben, to turn the Channel Islands into an "impregnable fortress".
In the course of 1942, one twelfth of the resources funneled into the whole Atlantic Wall was dedicated to the fortification of the Channel Islands.
Hitler had decreed that 10% of the steel and concrete used in the Atlantic Wall go to the Channel Islands.
It is often said the Channel Islands were better defended than the Normandy beaches, given the large number of tunnels and bunkers around the islands.
By 1944 in tunneling alone, 244,000 cubic meters (8,600,000 cu ft) of rock had been extracted collectively from Guernsey, Jersey, and Alderney (the majority from Jersey).
At the same point in 1944 the entire Atlantic Wall from Norway to the Franco-Spanish border, excluding the Channel Islands, had extracted some 225,000 cubic meters (7,900,000 cu ft)
.
Most of the WW2 Bunkers and Command posts are easily accessible and contain a wealth of information and construction details like authentic air vent systems in bunker walls along with 1940's trenches leading to the battery guns and sleeping quarters
Guernsey is well worth a visit - with many of the 1940's Bunkers being re-opened and restored with authentic German WW2 field gear.

The Gibraltar of the Caribbean at War! The Coastal Defenses of Puerto Rico during World War Two

Audio visual production from the Centro de Diseño y Producción de Recursos Instruccionales (CEDPRI) de la Universidad de Puerto Rico en Humacao. The half-hour documentary film was made by Dr. Gerardo M. PiñeroCádiz in 2013 and tells the story of preparing the island of Puerto Rico for the coming of war.

The film aims to rescue from oblivion the defensive sites built by the U.S. ArmyCorps of Engineers on the island of Puerto Rico during the 1940s, and their relation to other military installations. We will also highlight their importance during the war emergency and briefly explain their operations.
Just months into World War II, the United States would grant Puerto Rico the same strategic importance that the Spanish Empire had given it in the past. The “Gibraltar of the Caribbean” had just become one of the most important parts of American defense system in the West Indies. Air bases, naval and ground systems, communications, roads, and all kinds of military installations transformed Puerto Rico into one of the most important strategic points in the Atlantic for the successful defense of commercial maritime routes, the Allied supply lines, troop movements, Caribbean oil transit, and the Panama Canal itself.
To protect the military facilities, already built or under construction, from ground, aerial or naval attack, or sabotage, it was agreed to start the deployment of defenses, such as the coast artillery. Aside from protection, these defenses would lend support to ships while approaching, in transit, or sailing away from Puerto Rico.

A bit of History:
in 1940The Germans did not realize that the islands had been demilitarized and they approached them with caution.
The GermanLuftwaffe Reconnaissance flights were inconclusive.
But late at night on 28th June 1940, they sent a squadron of bombers over the islands and bombed the harbours of Guernsey and Jersey.
In St. Peter Port, the main town of Guernsey, some lorries lined up to load tomatoes for export to England were mistaken by the reconnaissance flights for troop carriers !
A similar attack occurred in Jersey where 9 died.
In total, 44 islanders were killed in the raids.
The BBC broadcast a belated message that the islands had been declared "open towns" and later in the day reported the German bombing of the island.
While the Wehrmacht was preparing Operation Grünpfeil (Green Arrow), a planned invasion of the islands with assault troops comprising of:
2 battalions
A reconnaissance pilot, Hauptmann Liebe-Pieteritz, made a test landing at Guernsey's deserted airfield on 30th June to determine the level of defense. There was none what so ever !
He reported his brief landing to Luftflotte which came to the decision that the islands were not defended.
A platoon of Luftwaffe airmen was flown that evening to Guernsey by Junkers transport planes.
Inspector Sculpher of the Guernsey police went to the airport carrying a letter signed by the bailiff stating that "This Island has been declared an OpenIsland by His Majesty's Government of the United Kingdom.
There are no armed forces of any description. The bearer has been instructed to hand this communication to you. He does not understand the German language."
He found that the airport had been taken over by the Luftwaffe.
The senior German officer, MajorAlbrecht Lanz, asked to be taken to the island's chief man.
They went by police car to the Royal Hotel where they were joined by the bailiff, the president of the controlling committee, and other officials. Lanz announced through an interpreter that Guernsey was now under German occupation.
In this way the Luftwaffe pre-empted the Wehrmacht's invasion plans.
Jersey surrendered on 1st July 1940.
Alderney, where only a handful of islanders remained, was occupied on 2nd July and a small detachment traveled from Guernsey to Sark, which surrendered on 4th July 1940.
The first ship-borne German troops consisting of two anti-aircraft units, arrived in St. Peter Port on the captured freighter SS Holland on 14th July 1940.
The German forces quickly consolidated their positions.
They brought in infantry, established communications and anti-aircraft defenses, established an air service with occupied mainland France, and rounded up British servicemen on leave.
The Channel Islands were amongst the most heavily fortified parts of the Atlantic Wall, particularly Alderney which is the closest to France.
On 20th October1941Hitler signed a directive, against the advice of Commander-in-Chief von Witzleben, to turn the Channel Islands into an "impregnable fortress".
In the course of 1942, one twelfth of the resources funneled into the whole Atlantic Wall was dedicated to the fortification of the Channel Islands.
Hitler had decreed that 10% of the steel and concrete used in the Atlantic Wall go to the Channel Islands.
It is often said the Channel Islands were better defended than the Normandy beaches, given the large number of tunnels and bunkers around the islands.
By 1944 in tunneling alone, 244,000 cubic meters (8,600,000 cu ft) of rock had been extracted collectively from Guernsey, Jersey, and Alderney (the majority from Jersey).
At the same point in 1944 the entire Atlantic Wall from Norway to the Franco-Spanish border, excluding the Channel Islands, had extracted some 225,000 cubic meters (7,900,000 cu ft)
.
Most of the WW2 Bunkers and Command posts are easily accessible and contain a wealth of information and construction details like authentic air vent systems in bunker walls along with 1940's trenches leading to the battery guns and sleeping quarters
Guernsey is well worth a visit - with many of the 1940's Bunkers being re-opened and restored with authentic German WW2 field gear.
